Did you ever notice problems with getting trouble codes 41, and 91 (oxygen sensors showing lean mixture), or any problems related to oxygen sensors or running rich when you installed the longtube headers? I've heard that this can cause the oxygen sensors to show a lean mixture, causing the engine to run rich. I believe I'm currently having this problem, and was wondering how you guys solved the issue.
I have MAC longtubes and I didn't use the o2 sensor extenders, by the way. My harness was long enough, apparently.
Thanks! Any and all responses are much appreciated!
